I hadn't noticed the back of the cab cut away. I suppose if the doors shut and latch OK, it will be alright. Well, except that the back of the cab is the only anti-crush structure in the D21 cab. The windshield always comes in during a roll over, but the back of the cab protects the driver's noggin.
Maybe when you get it running, you can slap a roll bar behind the seats for good measure, if there's not one there already. :-)

I'll update with a few pics from the back. Someone deinitely took out the back of the cab at some point, but they did a pretty decent job of it --doesn't just look like a hack job.

Not sure where to find the build date.. I could probably use the VIN to find it?

RE: to XoX -- the exhaust is grey colored, I didn't see any water. I'll look under the radiator cap to see what that looks like. I agree that it wants to run.

Parts are on the way, will arrive next week Monday and we'll start tinkering.

Thanks for all the replies!

Update 10/20

Replaced the fuel filter.
Fuel pump is definitely working, plenty of fuel in the line.
Still only runs if I pour gas down the top of the throttle body.

Could it be injectors? It looks like there is 2 injectors right on top of the throttle body (each have 2 wires connected to them). I didn't see a simple way to remove them -- just tug on the wires a little until they come loose?

Could it be fuel pressure regulator? I'm not sure where it is or how to test.

Or is it an electrical issue: Side note: the lights do not turn on, nor the 4 ways. So the ignition does, the dash lights up, but not headlights.... Do I have a wiring issue and is that preventing my injectors from working?

What should I try next? Again, thanks in advance for the help.

I know the injectors can get stuck, at least that's my experience with the newer design that sits in the fuel rail. I have to tap them with a hammer to break the years of fuel causing them to stick.

I guess you need to check your fuel injectors. The EC section of the 1989 Service Manual should have a way to test them.

Mine are not on the rail, but right on top.

I'm just not sure how to pull them out to test them -- I don't think I want to take the entire throttle body off/apart, but also not sure I want to yank too hard on the wires....

I could try the tap with the hammer move ... have done that with other machines in the past...

Have you checked codes yet? Here, I copy/pasted my reply from another thread about the early model like you have. ECU is under the passenger seat. The wrench/socket size you'll need is 12mm.

Candace, if you haven't seen it yet, here's a sticky with a video on getting those error codes

http://www.infamousnissan.com/forum/showthread.php?t=31527
Since yours in a 1986, scroll down to the bottom of that post. Start at the second video. Yours does not have a place for a screwdriver. It only has a toggle switch that selects between running data and stored data.

Expose the ECU, set the brake, shift into neutral' and turn the key to "ON" without starting it. You should see the LEDs flashing in sequence. If not, flip the switch the other way.

Now, fully press and release the gas pedal one time.
Press the clutch and shift into first. Release the clutch.
Press the clutch and shift back into neutral. Release the clutch.

The only code you should see is 44. Four long blinks followed by four short blinks.

Alright, ran the codes:

I see:

24 (throttle valve switch)
31 (ECU)

Soooo, I think I can figure out throttle valve switch, but what about ECU? Do I need ti replace the ECU?

------------------------------------------------------------------------------------------------------------------------------------

EDIT: I did some searching and saw what other people were saying about code 24: Pressing the gas pedal tests the throttle valve switch, so I tried again and I made sure to press the gas pedal several times. Now the codes I'm seeing are:

31 (ECU)
32 (EGR Function) [BUT this one is probably accounted for, because I've disconnected the air intake manifold while I'm looking around at all this]
43 (Throttle Position Sensor)

(I no longer see code 24)

So I guess the throttle valve switch is not the problem, but instead it's the throttle position sensor? Meanwhile, still not sure what the ECU error code is saying... why is the ECU telling me that the ECU is not working?

Any way you can post that 86.5 FSM? I'd love a copy.
